Application filed September 15, 1913.

To all whom it may concern Be it known that I, LOUIS VVEGLEIN, Jr., a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Primer and Speeder for Internal- Combustion Engines, of which the following is a specification.

My invention consists of an improved primer and speeder for internal combustion engines in which the liquid fuel is injected into the engine cylinder combined with heated or warmed air.

It further consists of such an improved primer and speeder in which the mixed liquid and heated air is drawn in finely comminuted condition into the intake of the engine.

It further consists of such a device which is controlled from the dashboard.

It further consists of means for causing the priming fuel to trickle in fine streams into the intake, thereby permitting perfect vaporization.

It further consists of improved means for heating the air.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings-Figure 1 represents a side elevation of an automobile engine provided with my primer and speeder, a part of the dashboard being shown in section. Fig. 2 represents a detail view illustrating the connection of the primerpipes into the intake-pipes. Fig. 3 repre sents a section on the line m-m in Fig. 2. Fig. 4 represents a detail view, partly in section, of the priming-cup. Fig. 5 represents a detail view illustrating the means for controlling the cock for said cup. Fig. 6 represents a side elevation of an automobile engine provided with a slightly different form of embodiment of my invention. Fig. 7 represents a longitudinal sectional view of the air-heating pipe. Fig. 8 represents a detail view of a part of said pipe and the exhaust-pipe. Fig. 9 represents a section on the line g z in Fig. 8. Fig. 10 represents a sectional detail view of the cold-air Specification of Letters Patent.

intake. Fig. 11 represents a view of the levers controlling the valves of the device. Fig. 12 represents a perspective view of the rack for said levers.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, the reference numeral 1 indicates an automobile engine of any suitable or desired make and construction, having a carbureter, 2, and a gaspipe, 8, conveying the gas-mixture to the cylinders of the engine from said carbureter.

In the embodiment of my invention disclosed in Figs. 1 to 5, an air heating and moistening device is disclosed similar to that disclosed in an application for Letters Patent, Serial No. 777,682, filed by me on July 7, 1913, in which air is taken into a tank or casing, 4, and conveyed through a pipe, 5, adjacent the cylinders to the intake of the carburetor.

A primer-tank, 6, containing gasolene or whatever liquid fuel is used in the engine, is supported upon the dashboard of the car, and has a pipe, 7 controlled by a cock, 8, leading from it to a primer-cup, 9, supported adjacent the engine. Said cup has the fuel-pipe entering its side, and has an air-pipe, 10, entering its detachable cover, 11. A cock-barrel, 12, is formed at the lower end of the cup, and has a plug, 13, seated therein and drawn to its seat by a spring, 14, upon its shank. Said plug is formed with an oval port, 15, corresponding to the port of the cup, and the outlet of the cock communicates with a T-coupling, 16, from which branch two pipes, 17, which enter the heads, 18, of the branches of the intake pipe which are connected to the intakes of the engine-cylinders immediately at the intake valves. The ends of said primingpipes are closed and the portions within the heads of the intake pipes are formed with perforations, 19, upwardly diverging at an angle of forty-five degrees to each other. The cock of the priming-cup has an arm, 20, to which is connected a rod, 21, the rear end of which is connected to an arm, 22, upon a rock-shaft, 28, journaled upon the dashboard and carrying a lever, 24:, which engages a rack, 25, upon the side of the coilbox, 26, upon the dash. A spring, 27, is coiled around the rook-shaft and tends to rock the same to tilt the lever forward and the arm rearward to pull upon the connecting-rod and, through it, upon the arm of the cock to close the same. The airpipe, 10, leads from the hot-air pipe to the top of the priming cup. In case the primer and speeder is applied to an engine not provided with the air-heating and moistening device, the intake end of said pipe will be placed in close proximity to the nearest and most convenient hot part of the engine.

In Figs. 6, 7, 8, 9, 10, 11 and 12 my invention is illustrated as applied to an engine which is not provided with the heating and moistening device. In this device an airpipe, 29, having a flat side, 30, is secured alongside of and in contact with the exhaust-manifold, 31, which also has a flat side, and said air-pipe is bent downward and forward and connected to the carbureter. The air-pipe has a closed forward end, and is formed with two ports, 32, near such end. A valve, 33, is pivoted at its middle upon the side of the air-pipe and has an ear, 34, to which a connecting-rod, 35, is pivoted, which rod has its rear end connected to an arm, 36, upon arock-shaft, 37 journaled upon the dashboard and having a lever, 38, for rocking it, and a spring, 39, for throwing the lever forward. The airpipe has an annular series of ports, 40, near the end entering the earbureter, and an annular seat, 41, in which an annular valve 42, is rotatably seated,said valve having ports, 43, which may be brought to register with the ports in the seat. A rack, 44, having notches in both sides, is secured upon the dash to project between and be en gaged by the two levers controlling the airvalve and the primer cock.

In both forms illustrated the air for the carbureter is heated. In the first-described form, the air is heated and moistened in the tank alongside the engine. In the second form, the air is heated by passing through the pipe in direct contact with the exhaustpipe. The intake of cold air is regulated in both instances,-in the first-described form, as described in my earlier patent application, above referred to, and in the second-described form, by the valve 33.

When the engine is started and it is necessary to prime the same, the cock of the primer-tank and the cock of the primer-cup are opened and the engine cranked. Air and fuel will be drawn by suction from the primer-cup and the liquid fuel will trickle in minute streams through the inclined openings in the priming-pipes into the intake of the engine cylinders immediately at the intake valve and, on account of the comminution of the fuel, vaporization will quickly take place and explosion follow.

When the engine is hot and the air is, consequently, heated, vaporization is instantaneous. When the device is employed as a speeder, the air passing into the primercup is naturally heated from the running engine and the mixture is enriched and increased in quantity, thus speeding up the engine. The device is under control from the operators seat and the quantity of fuel admitted through the same can be varied according to requirements. As the cap of the primer-cup is removable, cleansing fluid, such as alcohol, coal oil or other fluid may be poured through the cup without necessitating the removal of any part of the engine. Admission of cold air into the carbureter can be controlled by the annular valve upon the air-pipe.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth, respectively, in the following claims are employed.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. A primer and speeder for internal combustion engines, comprising a branched gas pipe having heads connected to the intakes of the engine, an air duct arranged to be heated by its proximity to the engine, a primer cup, a pipe connected to said cup and air duct, controlled means for supplying fuel to said cup, and controlled pipes connected to said cup and entering the heads of the gas pipe and formed within such heads with perforations diverging upwardly and outwardly.

2. A primerand Speeder for auton'iobile engines, comprising a branched gas pipe having heads connected to the intakes of the engine, an air duct arranged to be heated by its proximity to the engine, a priming tank for containing liquid fuel, a primer cup, a controlled pipe connecting said tank and cup, a pipe connected to said air duct and cup, pipes connected to said cup and having their closed ends within the heads of the gas pipe and formed with outwardly and upwardly diveiging perforations in their upper sides, a valve controlling said pipes, and means for operating such valve from the dashboard of the automobile.
